Abstract
Description
Technical Field
[0001] This application relates to the technical field of physical separation equipment, and in particular to a molding apparatus that maintains the quality of materials through solid-liquid separation. Background Technology
[0002] Containers, as the name suggests, are vessels used to hold materials. They are widely used not only in daily life but also in industrial manufacturing and other fields.
[0003] In the manufacturing industry, containers are typically used to hold pre-mixed materials (i.e., raw materials for product production and processing, usually solid-liquid mixtures). During the production and processing of products using molding equipment, materials need to be taken out of the container multiple times. Therefore, the quality of the produced product is closely related to the quality of the materials in the container.
[0004] However, due to the physical phenomenon of solid-liquid stratification (i.e., sedimentation) that occurs after materials are left to stand in a container for a period of time, and since production processes typically use materials from the top of the container, the quality of the materials taken from the container each time is inconsistent, leading to inconsistent product quality. Furthermore, as materials are used and consumed, the concentration of the materials in the container (i.e., the solid content) will significantly differ from the initial concentration. Therefore, staff need to periodically check the quality of the materials in the container and replace substandard materials promptly, resulting in material waste. Summary of the Invention
[0005] This application provides a molding apparatus that maintains material quality through solid-liquid separation. By controlling the solid-liquid separation function, the quality of the material can be controlled, reducing waste caused by substandard material quality, while effectively ensuring the processing and molding effect of the product.
[0006] This application provides a molding apparatus that maintains material quality through solid-liquid separation, employing the following technical solution:
[0007] A molding apparatus for maintaining material quality through solid-liquid separation includes a container, a body, an upper mold with a thermo-pressing function, a lower mold movably connected to the body, and a drive component for driving the lower mold to move.
[0008] The container includes a barrel, a filter element, a drain pipe, and a feed pipe;
[0009] The filter element is used to separate solids and liquids in the material. It is disposed inside the barrel and forms a material intake area and a filtrate area inside the barrel, with the filtrate area located below the material intake area.
[0010] The drain pipe is installed on the barrel, with one end connected to the filtrate zone, and is controlled by a pump to drive the liquid in the filtrate zone to be discharged.
[0011] The feeding pipe is installed on the barrel, with one end connected to the material taking area, and is controlled by the pump to drive the material into the material taking area;
[0012] The container also includes an aeration mixer; the aeration mixer is mounted on the barrel body, and its functional end is located in the material intake area;
[0013] The aeration mixer includes a first impeller for clearing blockages in the filter element; the first impeller is located in the filtrate zone, and rotates accordingly when the functional end is running;
[0014] The feeding pipe includes a first pipe section located inside the barrel and a second pipe section located outside the barrel, and the end of the first pipe section located in the feeding area is bent and opens downward;
[0015] The container also includes a linkage component;
[0016] The first pipe section is rotatably connected to the barrel body, and its rotation axis is parallel to the rotation axis of the first impeller; the linkage component enables the first impeller and the first pipe section to be linked, so that the first pipe section rotates with the first impeller.
[0017] The first pipe section is provided with a second impeller in the filtrate zone for clearing blockage of the filter element, and the axis of the second impeller coincides with the rotation axis of the first pipe section;
[0018] The upper mold, the container, and the driving component are all fixedly mounted on the machine body. The upper mold is located above the container, and the driving component is located below the container. The lower mold moves vertically and moves in and out of the material handling area.
[0019] When the lower mold enters the material taking area, the first pipe section and the functional end are located on both sides of the lower mold.
[0020] By adopting the above technical solution, when the solid content of the material in the feeding area decreases due to repeated feeding, new material can be directly added to the feeding area through the feeding pipe. At the same time, the liquid after solid-liquid separation can be discharged into the filtrate area through the drain pipe, thereby controlling the solid content of the material inside the container and controlling the quality of the material to be fed into the container. This reduces waste caused by the material becoming unusable due to a decrease in solid content, and effectively ensures the processing and molding effect of subsequent products. Furthermore, during the operation of the aeration mixer, it and the first pipe section can respectively play a stirring and unblocking role on both sides of the internal space of the container, thereby effectively ensuring the processing and molding effect of the product after feeding.
[0021] Optionally, two guide frames are provided on both sides of the lower mold, and the lower mold slides in cooperation with the machine body through the guide frames.
[0022] By adopting the above technical solution, the stability of the lower mold relative to the machine body during the movement process can be improved, thereby improving the alignment accuracy between the upper and lower molds, and thus improving the quality of the material hot-pressed between the upper and lower molds.
[0023] Optionally, the guide frame includes a connector fixedly connected to the machine body, a slider slidably connected to the connector, and a plurality of third impellers;
[0024] The end of the sliding member away from the connecting member is slidably connected to the lower mold, and the sliding resistance between the lower mold and the sliding member is less than the sliding resistance between the sliding member and the connecting member; the third impeller is rotatably disposed on the connecting member, located in the material picking area, and its rotation drives the material to surge upward; during the sliding process of the sliding member relative to the connecting member, the sliding member drives several of the third impellers to rotate.
[0025] When the sliding member moves downward to its limit relative to the connecting member and the lower die moves downward to its limit relative to the sliding member, the lower die is completely immersed in the material, and the third impeller is close to the top of the lower die; when the sliding member moves downward to its limit relative to the connecting member and the lower die moves upward to its limit relative to the sliding member, the top of the lower die is located above the material taking area.
[0026] By adopting the above technical solution, the lower mold can drive the third impeller to rotate and cause the material to surge during its upward movement above the material, and it can also drive the third impeller to rotate and cause the material to surge during its downward movement within the material. This allows the material to be evenly stirred after the lower mold leaves the material, and it can drive the material to move towards its top after the lower mold enters the material to facilitate rapid material removal. Furthermore, it can prevent the amount of material removed by the lower mold from being affected by the rotation of the third impeller during the upward movement of the lower mold within the material.
[0027] Optionally, the two guide frames are located on both sides of the lower mold, excluding the first pipe section and the functional end.
[0028] By adopting the above technical solution, the area around the lower mold in the material taking zone can be subjected to a stirring effect, thereby effectively ensuring the stirring of materials and improving the uniformity of solid distribution in the materials.
[0029] In summary, this application includes at least one of the following beneficial effects:
[0030] 1. It can control the solid content of the material inside the container according to the demand, thereby controlling the quality of the material, reducing waste caused by the material failing to meet the standard due to the decrease in solid content, and effectively ensuring the processing and forming effect of subsequent products.
[0031] 2. It can improve the uniformity of solid distribution in materials, thereby effectively ensuring the quality of products obtained from subsequent material processing and molding;
[0032] 3. It can improve the stability and reliability of the filter element in solid-liquid separation of materials, and can also clear blockages in the filter element while stirring the materials;
[0033] 4. During the lower die's movement, the third impeller can be driven to tumble the material in the material feeding area according to its position, so as to achieve the corresponding auxiliary upper die to complete the material feeding effect, while reducing the probability that the material tumbling will affect the material feeding amount of the upper die.

[0040] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail. Example 1
[0041] Reference Figure 1 This application discloses a container that maintains material quality through solid-liquid separation, used to provide materials with a solid content that meets the standards for product processing and molding.
[0042] The container includes a barrel 11 for holding materials, a filter element 12 for solid-liquid separation of materials, a drain pipe 13 for discharging liquid, a feed pipe 14 for replenishing new materials, and an aeration mixer 15 for mixing materials.
[0043] The container body 11 has a rectangular parallelepiped structure with an opening at its top. The filter element 12 has a plate-like structure and is fixedly installed in the container body 11 parallel to the opening. It divides the internal space of the container body 11 into a material intake area 111 and a filtrate area 112. The material intake area 111 is located on the side of the filtrate area 112 closest to the opening of the container body 11. Liquid in the material can pass through the filter element 12, and the filter element 12 can intercept solids in the material. The container is used with the opening facing upwards. When it contains material, the filtrate area 112 contains liquid, and the material intake area 111 contains both solids and liquid. In this embodiment, it is preferable that the space of the material intake area 111 is larger than the space of the filtrate area 112. Since the filter element 12 with the above functions is common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.
[0044] The drain pipe 13 is fixedly installed based on the barrel body 11. One end of the drain pipe 13 penetrates into the interior of the barrel body 11 and communicates with the filtrate zone 112. The drain pipe 13 is controlled by a pump to discharge the liquid in the filtrate zone 112. In this embodiment, it is preferable that the drain pipe 13 penetrates into the interior of the barrel body 11 vertically from the bottom of the barrel body 11, and preferably the drain pipe 13 communicates directly with the bottom of the filtrate zone 112.
[0045] The feed pipe 14 is fixedly installed based on the barrel 11. One end of the feed pipe 14 penetrates into the interior of the barrel 11 and communicates with the material collection area 111. It is controlled by another pump to drive new material through the feed pipe 14 into the material collection area 111. In this embodiment, it is preferable that the feed pipe 14 also penetrates into the interior of the barrel 11 vertically from the bottom of the barrel 11, and preferably, the feed pipe 14 passes through the filter element 12 and communicates directly with the bottom of the material collection area 111.
[0046] The aeration mixer 15 is fixedly installed on the barrel 11. Its functional end 151 is inserted into the barrel 11, and the end of the functional end 151 is located in the material intake area 111. During operation, it can agitate the material around the functional end 151. In this embodiment, the power structure of the aeration mixer 15 is preferably fixedly installed below the barrel 11. The functional end 151 is inserted vertically into the interior of the barrel 11 from the bottom of the barrel 11, and enters the material intake area 111 after passing through the filter element 12. Since the aeration mixer 15 with the above functions is common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.
[0047] The implementation principle of a container for maintaining material quality through solid-liquid separation according to an embodiment of this application is as follows:
[0048] The material contained in the container is used for product processing and molding. As the product is processed and molded, the solid content in the material taking area 111 decreases, which will affect the effect of subsequent product processing and molding, and thus affect the quality of the final product.
[0049] Therefore, when the solid content in the feeding zone 111 decreases, new material can be fed into the feeding zone 111 through the feeding pipe 14. At the same time, the liquid discharge pipe 13 is controlled to discharge the liquid in the filtrate zone 112, and the aeration mixer 15 is controlled to stir the material in the feeding zone 111. This ensures that the solid content in the feeding zone 111 is evenly distributed while maintaining the required range, thereby effectively guaranteeing the product processing and molding effect. Example 2
[0050] Reference Figure 2 The difference between this embodiment and embodiment 1 is that the feeding pipe 14 and the aeration mixer 15 are used to further improve the uniformity of the solid distribution of the material in the feeding zone 111, and at the same time, can effectively ensure that the filter element 12 can perform solid-liquid separation of the support in a long-term stable manner.
[0051] The aerator 15 has a first impeller 152 fixedly installed at the root of its functional end 151. The axis of the first impeller 152 is vertical and coincides with the axis of the functional end 151, and the first impeller 152 is located at the bottom of the filtrate zone 112. During the operation of the aerator 15, the first impeller 152 will rotate with the functional end 151. During its rotation, it can drive the liquid in the filtrate zone 112 to flow towards the filter element 12, thereby clearing the filter element 12 and reducing the probability of solids accumulating and clogging the surface of the filter element 12.
[0052] The feeding pipe 14 includes a first pipe section 141 located inside the barrel 11 and a second pipe section 142 located outside the barrel 11. The first pipe section 141 and the second pipe section 142 are connected and communicate with each other. The end of the first pipe section 141 away from the second pipe section 142 is bent so that its opening faces downward, allowing new material to enter the feeding area 111 downward through its opening. This reduces the influence of old material in the feeding area 111 on the new material entering the feeding area 111 along the feeding pipe 14, and also reduces the probability that solids in the old material in the feeding area 111 will block the opening at the end of the first pipe section 141. In this embodiment, it is preferable that the portion of the first pipe section 141, except for its end, extends vertically, and preferably the extension trajectory of the end of the first pipe section 141 is a semicircle.
[0053] A second impeller 143 is fixedly installed at the root of the first pipe section 141. The axis of the second impeller 143 is vertical and coincides with the axis of the root of the first pipe section 141, and the second impeller 143 is located at the bottom of the filtrate zone 112. A linkage 16 for linking the first impeller 152 and the second impeller 143 is installed at the bottom of the filtrate zone 112 on the barrel 11. The linkage 16 is connected to the first impeller 152 and the second impeller 143 respectively, so that the first impeller 152 can drive the second impeller 143 to rotate through the linkage 16 during the rotation of the first impeller 152. During the rotation of the second impeller 143, the liquid in the filtrate zone 112 can also be driven to flow towards the filter element 12, thereby also clearing the filter element 12 and further reducing the probability of solids accumulating and clogging the surface of the filter element 12. In this embodiment, the linkage 16 is preferably a synchronous belt or synchronous chain. Since the linkage 16 with the above functions is a common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.
[0054] The implementation principle of a container for maintaining material quality through solid-liquid separation according to an embodiment of this application is as follows:
[0055] The material contained in the container is used for product processing and molding. As the product is processed and molded, the solid content in the material taking area 111 decreases, which will affect the effect of subsequent product processing and molding, and thus affect the quality of the final product.
[0056] Therefore, when the solid content in the feeding zone 111 decreases, new material can be fed into the feeding zone 111 through the feeding pipe 14. At the same time, the liquid discharge pipe 13 is controlled to discharge the liquid in the filtrate zone 112, and the aeration mixer 15 is controlled to stir the material in the feeding zone 111. This ensures that the solid content in the feeding zone 111 is evenly distributed while maintaining the required range, thereby effectively guaranteeing the product processing and molding effect. Example 3
[0057] Reference Figure 3 and Figure 4 This application discloses a molding apparatus that maintains material quality through solid-liquid separation, used to process and shape materials after taking them from container 1 to obtain products.
[0058] The molding apparatus includes a container 1, as disclosed in Example 2, which maintains the quality of the material through solid-liquid separation, and also includes a body 2 as the mounting base for other structures, an upper mold 3 with a hot-pressing function, a lower mold 4 movably connected to the body 2, and a drive member 5 for driving the lower mold 4 to move.
[0059] The machine body 2 has a cubic structure with a square cross-section and is fixedly installed on the ground in a vertical position. The upper mold 3 is installed on the top of the machine body 2, and the lower mold 4 is movably installed on the bottom of the machine body 2. Its movement direction is vertical and its top has a groove for picking up materials. The lower mold 4 and the upper mold 3 are aligned along the movement direction of the lower mold 4. The driving component 5 is also installed on the bottom of the machine body 2. It is located below the lower mold 4 and is used to drive the lower mold 4 to move relative to the machine body 2. The container 1 is fixedly installed on the bottom of the machine body 2 with the opening of the barrel 11 vertically upward. During the process of the driving component 5 driving the lower mold 4 to move, the lower mold 4 moves in and out of the picking area 111. In this embodiment, the preferred driving component 5 is a hydraulic cylinder, whose piston rod passes through the barrel 11 and the filter 12 and is connected to the lower mold 4. The feeding pipe 14 and the drain pipe 13 are located on both sides of the piston rod. Preferably, the cross-sections of the upper mold 3, the lower mold 4 and the container 1 are square, and the size of the lower mold 4 is smaller than the size of the container 1. Since the upper mold 3, the lower mold 4 and the driving component 5 with the above functions are all common existing technologies, they will not be described in detail here, and they are only briefly shown in the accompanying drawings.
[0060] Reference Figure 4 and Figure 5After the container 11 is filled with material, when the control drive 5 drives the lower mold 4 to move downward to its limit position, the lower mold 4 is completely immersed in the material in the material taking area 111. The lower mold 4 will take the material through the groove on its top. Then, when the control drive 5 drives the lower mold 4 to move upward to its limit position, the lower mold 4 contacts the upper mold 3. The material is located in the forming cavity between the upper mold 3 and the lower mold 4. The material taken by the lower mold 4 is heated and pressurized by the bottom of the upper mold 3, so that the material can be finally hot-pressed into the desired product.
[0061] Reference Figure 3 and Figure 4 Furthermore, when the lower mold 4 moves downward to its limit position, a space is formed between it and the filter element 12 for the first pipe section 141 of the feeding pipe 14 to rotate and the functional end 151 of the aeration mixer 15 to stir the material. Preferably, the first pipe section 141 and the functional end 151 are close to the inner walls of opposite sides of the barrel 11.
[0062] Furthermore, to improve the stability of the lower mold 4 relative to the body 2, it is preferable that guide frames 6 are installed on both sides of the body 2, and the lower mold 4 forms a sliding fit with the body 2 through the guide frames 6. In this embodiment, it is preferable that the two guide frames 6 are respectively installed on both sides of the lower mold 4 that are not adjacent to the first pipe section 141 and the functional end 151.
[0063] The guide frame 6 includes a connector 61 mounted on the machine body 2, a sliding member 62 mounted on the lower mold 4, and multiple third impellers 63 for mixing materials.
[0064] The top of the connector 61 is fixedly connected to the machine body 2 and located above the barrel 11, while its bottom is located in the material feeding area 111 and immersed in the material. One end of the sliding member 62 is slidably connected to the lower mold 4, and the other end is slidably connected to the bottom of the connector 61, with both sliding directions being vertical. The third impeller 63 is rotatably installed on the bottom of the connector 61, with its rotation axis being vertical and completely immersed in the material feeding area 111. Multiple third impellers 63 are evenly distributed along the length of the connector 61. During the sliding process of the sliding member 62 relative to the connector 61, it drives multiple third impellers 63 installed on the corresponding connector 61 to rotate synchronously and in the same direction. In this embodiment, the sliding member 62 preferably has a space for material to pass through, ensuring the stirring effect of the third impeller 63 on the material; and preferably, a gear set structure is installed between the sliding member 62 and the connecting member 61, so that the sliding member 62 can slide through the gear set structure to drive the multiple third impellers 63 to rotate; since the gear assembly structure with the above functions is a common prior art, it will not be described in detail here, and its expression is omitted in the drawings.
[0065] During the movement of the lower mold 4 relative to the body 2, due to the linkage between the sliding member 62 and the corresponding multiple third impellers 63 during the sliding of the sliding member 62 relative to the connecting member 61, the resistance that the sliding member 62 needs to overcome relative to the connecting member 61 will be much greater than the resistance that the lower mold 4 needs to overcome relative to the sliding member 62 during the movement.
[0066] Reference Figure 4 and Figure 5 When the lower mold 4 moves downward to its limit position, the lower mold 4 slides downward to its limit position relative to the sliding member 62, and the sliding member 62 also slides downward to its limit position relative to the connecting member 61. At this time, during the upward movement of the lower mold 4, it first slides upward relative to the sliding member 62. When it slides upward relative to the sliding member 62 to its limit position, its top is above the liquid surface of the material in the material-taking area 111 (that is, the material taken by the lower mold 4 is above the liquid surface of the material in the container 1). Afterward, the lower mold 4 continues to move upward, which will drive the sliding member 62 to slide upward relative to the connecting member 61, thereby driving multiple third impellers 63 to rotate, preventing the material at the top of the lower mold 4 from being affected when the third impellers 63 rotate and stir the material. When the lower mold 4 moves upward to its limit position, the lower mold 4 slides upward relative to the sliding member 62 to its limit position, and the sliding member 62 also slides upward relative to the connecting member 61 to its limit position.
[0067] When the lower mold 4 moves upward to its limit position, the lower mold 4 slides upward to its limit position relative to the sliding member 62, and the sliding member 62 also slides upward to its limit position relative to the connecting member 61. At this time, during the downward movement of the lower mold 4, it first slides downward relative to the sliding member 62. When it slides downward to its limit position relative to the sliding member 62, its top is above the liquid surface of the material in the material collection area 111 and is about to be immersed in the material. Afterward, the lower mold 4 continues to move downward, which will drive the sliding member 62 to slide downward relative to the connecting member 61, thereby driving multiple third impellers 63 to rotate. The third impellers 63 rotate and stir the material, making the solid distribution in the material collection area 111 uniform and promoting the material to enter the groove at the top of the lower mold 4 to complete the material collection. When the lower mold 4 moves downward to its limit position, the lower mold 4 slides downward to its limit position relative to the sliding member 62, and the sliding member 62 also slides downward to its limit position relative to the connecting member 61.
[0068] Furthermore, to improve the quality and quantity of material taken out by the lower mold 4 after it is immersed in the material and to ensure that the material meets the requirements, it is preferable that the aeration mixer 15, the feeding pipe 14, and the drain pipe 13 all operate when the top of the lower mold 4 is above the material liquid surface.
[0069] The implementation principle of a molding apparatus that maintains material quality through solid-liquid separation according to an embodiment of this application is as follows:
[0070] During the product processing and molding process, the drive component 5 is first controlled to drive the lower mold 4 downward to its limit position, so that the lower mold 4 is immersed in the material and the material in the material taking area 111 enters the groove at the top of the lower mold 4 to complete the material taking; then, the drive component 5 is controlled to drive the lower mold 4 upward to its limit position, and at the same time, multiple third impellers 63 will also rotate as the lower mold 4 continues to move upward, so that the material in the material taking area 111 is kept in a uniform solid distribution, which is convenient for the next material separation and molding; after the lower mold 4 moves upward to its limit position, the upper mold 3 hot presses the material located at the top of the lower mold 4 to form a mold. During this process, the operator can control the operation of the aeration mixer 15, the feeding pipe 14 and the drain pipe 13 to keep the material in the barrel 11 at a certain mass;
[0071] After the product is hot-pressed and discharged, the control drive 5 drives the lower mold 4 to move downward to the limit position. When the top of the lower mold 4 is about to be immersed in the material, multiple third impellers 63 will rotate as the lower mold 4 continues to move downward, thereby promoting the flow of material in the material picking area 111, so that the material can enter the groove at the top of the lower mold 4 to complete the picking, thereby improving the efficiency of subsequent product processing and forming.
[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
